Abstract

Una hoja de acero laminada en caliente que contiene los componentes prescritos, que satisface la fórmula (1) con respecto a la cantidad agregada de Cr y Al, y que tiene una estructura metalográfica que tiene una fracción de volumen de ferrita de más de 90% pero 98% o menos, una fracción de volumen de martensita de 2% o más pero menos de 10% y una fracción de volumen de menos de 1% de una estructura restante que comprende una o más sustancias de entre perlita, bainita y austenita retenida, la ferrita tiene un diámetro de círculo equivalente promedio de 4 µm o más y un diámetro de círculo equivalente máximo de 30 µm o menos y la martensita tiene un diámetro de círculo equivalente promedio de 10 µm o menos y un diámetro de círculo equivalente máximo de 20 µm o menos. Fórmula 1: [Cr]x5+[Al]=0.50. En la fórmula (1), [Cr] es el contenido de Cr (% en masa), y [Al] es el contenido de Al (% en masa).A hot rolled steel sheet containing the prescribed components, which satisfies the formula (1) with respect to the aggregate amount of Cr and Al, and which has a metallographic structure that has a ferrite volume fraction of more than 90% but 98% or less, a fraction of martensite volume of 2% or more but less than 10% and a volume fraction of less than 1% of a remaining structure comprising one or more substances between retained perlite, bainite and austenite , the ferrite has an average equivalent circle diameter of 4 µm or more and a maximum equivalent circle diameter of 30 µm or less and the martensite has an average equivalent circle diameter of 10 µm or less and a maximum equivalent circle diameter of 20 µm or less. Formula 1: [Cr] x5 + [Al] = 0.50. In formula (1), [Cr] is the content of Cr (% by mass), and [Al] is the content of Al (% by mass).
